FREDERICK R. MEGAN, OF KANSAS CITY, MISSOURI.

DISINFEGTING APPLIANCE.

To all "whom it may concern Be it known that I, FREDERICK R. MEGAN, a citizen of the United States, residing at Kansas City, in the county of J ackson and State of Missouri, have invented certain new and useful Improvements in Disinfecting Appliances, of which the following is a specification.

This invention relates to disinfecting appliances, and my object is to provide an apparatus whereby the process of disinfecting or fumigating a building or an apartment may be performed effectively but in a materially shorter time than by the methods usually employed. In carrying out my invention therefore, I have devised an appa ratus for the purpose of generating a very active disinfecting agent, which apparatus, however, may be maintained inoperative until the building or compartment is closed in readiness therefor, whereupon the device may be set in action by means of a connection which may be manipulated from the outside of the compartment or building. The invention also contemplates the provision of suitable means for supporting the generating process by the production of air currents which will likewise convey the disinfectant throughout the interior of the building, appropriate conduits being also provided where desirable between the apparatus and the individual rooms to be treated.

With this object in view .the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1, is a vertical central section through one form of the appliance. Fig. 2. is a horizontal section on the line 1l-II of Fig. 1. Fig. 3, is an elevation partly in section of a modified form.

Referring to Figs. 1 and 2 of the drawing. the apparatus is here shown as comprising a pan 2 which is suspended within the top of a drum 4 having air inlet openings 6 in its base, above which is secured by bolts 8 a skeleton support 10, having a suitable motor 12 designed to operate a fan 14 for sucking air in openings 6 and driving the air up through openings 16 provided in the upper portion of the sides of the pan 2. The outer margin of this pan is fitted with Specification of Letters Patent.

Patented m. 17, 1914.

a ring forming a depending flange 18 for engaging the top of the drum 4, and also an upwardly projecting flange 20 for fitting inside the top casing or cover 22 when said cover is used, the same being provided with a series of spouts 24 to which connection may be made for conducting the disinfectant to individual rooms.

Extending across the pan 2 is a strip 26 for the purpose of supporting one end ofa slideway 28 upon which is carried centrally over the pan 2, a 'cup.30 fitted with a cap 32. A slide 34 is mounted in the slideway 28 and forms a movable bottom for dumping the contents of the cup 30. To the slide is secured a handle 36 operating through an opening in the flange 20, to which handle may be fastened a cable 38 whereby the slide may. be conveniently operated from any desired distance. Directly beneath the cup 30 is located a conical distributing member 40 which may be supported in any suitable manner. as by a cylindrical shell 42 fixed to the pan 2.

With the above construction a suitable solution 44:, containing a disinfecting agent, such as formaldehyde. may be placed in the pan which solution upon combining with an appropriate oxidizing powder 46. such as potassium permanganate, placed in the cup 30. will be rapidly decomposed to free the disinfectant. the powder being held in the cup by means of the slide 34. Upon withdrawing the slide. which may be done from the outside of the building by means of the cable 38. thereby avoding anv iniury from inhaling the fumes of the disinfectant. the contents of the cup are. dumped upon member 40 and distributed over all parts of the solution. The reaction being at once started, it is supported and accelerated by the air supplied from the fan, which meanwhile has been set in operation. The action of the fan also drives the air containing the fumes away from the appliance to the rooms which are to be disinfected.

Fig. 3, illustrates a modification in which the motor driven fan is dispensed with and the drum 4: is provided with partitions 48 in order to form a compressed air reservoir. having supply and discharge pipes 50 and 52 respectively, controlled by valves 54.

the discharge pipe leading to a point beneath the pan 2. By this means, with the compressed air reservoir properly charged and the valve of the pipe 52 open, an air blast may be obtained similar to that produced by the fan, with similar results.

From the foregoing it will be apparent that I have produced a disinfecting appliance possessing the features of advantage enumerated as desirable and I wish it to be understood that while I havc illustrated and described two forms which my invention is designed to take, I reserve the right to make all changes properly falling within the spirit and scope of the appended claims.

I claim: 1

1. In a disinfecting appliance, a drum, a receptacle supported within and completely partitioning said drum, said receptacle being provided with a series of perforations in the sides thereof, a second receptacle overlying said first receptacle and provided with means for dumping the contents thereof into the first receptacle, and means for inducing a blast of air upward through said perforations.

2. In a disinfecting appliance, a drum, a receptacle supported within and completely partitioning said drum, said receptacle being provided with a series of perforations in the sides thereof, a'second receptacle overlying said first receptacle and provided with a movable bottom and means whereby said bottom may be operated to dump the contents of said second receptacle into the first receptacle, and means for inducing 'a current of air upward through said perforations 3. In a disinfecting appliance, a drum, a

niraaia receptacle supported within and completely partitioning said drum, said receptacle being provided with a series of perforations in the sides thereof, a second receptacle overlying said first receptacle and provided with a slidable bottom and means whereby said bottom may be operated to dump the contents of said second receptacle into the first receptacle, a conical distributing member underlying said second receptacle for deflecting said contents toward the sides of said first receptacle, and means for inducing a blast of air upward through said perforations.

4C. In a disinfecting appliance, a receptacle provided with a series of side perforations, and adapted to contain a solution, a"

receptacle overlying said first receptacle and adapted to contain a compound which will combine with the solution to free a disinfectant, said second receptacle being provided with means whereby said compound may be dumped into said solution, a cover for said first receptacle and inclosing said second receptacle and provided with one or more distributing spouts, and means for inducing a current of air inward through said perforations and out through said spouts.

In testimony whereof, I affix my signature, in the presence of two witnesses.
